How do you get it running?

Difficulty · easy Time to first run · 5min

Default install is sideloading the Android APK and running the bundled portable Windows EXE, building from source needs JDK 11, Android SDK 34, and Node.js 18.

Apache 2.0 lets anyone use, modify, and distribute the code, including commercially, with attribution and an explicit patent grant.

In plain English

DeCloud is a free app for moving files between an Android phone and a Windows PC over your home WiFi or a USB cable. The whole point is that files travel directly between the two devices on your local network. Nothing is uploaded to a cloud server, you do not create an account, and the project is open source so you can read the code to confirm what it does. It is pitched as an alternative to AirDrop and Quick Share for people who do not want a third party in the middle. The README highlights that you can back up an entire phone in minutes on your own network, with no internet connection required. The main features cover transferring any file or folder, searching across internal storage and SD card with type, size, and date filters, and quick categories for images, videos, audio, documents, downloads, and apps. There is contacts export to a standard VCF file, a real time progress bar based on bytes rather than file count, light and dark themes, and three transfer modes: a WiFi hotspot from the phone, a shared WiFi network, or USB with ADB. The app has no ads, no accounts, and no internet access. A Google Play release is listed as coming soon, and the current way to install is to sideload the APK from GitHub Releases. A portable Windows companion executable is bundled in the same release with no installer needed. For people who want to build from source, the Android app uses Gradle with JDK 11 and Android SDK 34 or higher, and the desktop app is an Electron project that needs Node.js 18 or newer. The license is Apache 2.0.
